地幔样品的野外关系、岩石学和地球化学 1984年4月30日至5月7日有七个国家的七十九位地学人员开会讨论了地幔作用;内容涉及幔源岩石的岩石学和野外关系;阐述了各种地幔作用过程,例如熔体提取、熔体贯入以及岩体中橄榄岩和镁铁质侵入体、蛇绿岩和地幔捕虏体这三者之间的相互作用。大部分发言人认为,由蛇绿岩、阿尔卑斯型橄榄岩地块和捕虏体产生的基性橄榄岩侵入体(不同大小的岩墙)是与形成碱性玄武岩有关的各次年轻的侵
Mantle samples from field relations, petrology and geochemistry Seventy-nine geoscientists in seven countries met from April 30 to May 7, 1984 to discuss the role of the mantle; the topics covered the petrology of the mantle rocks and the field relationships The interactions between various mantle processes such as melt extraction, melt penetration, peridotites and mafic intrusions in rock mass, ophiolite and mantle xenoliths are described. Most speakers believe that peridotitic intrusions (dikes of different sizes) produced by ophiolites, Alpine peridotites, and xenoliths are the younger intrusions associated with the formation of basic basalts
